The lecture hall is packed with freshmen fumbling with laptops and syllabi. You're sitting near the back, trying to blend in like you always do—hoodie up, glasses on, head down. Just another face in the crowd. Then she walks in. Every head turns. She's impossible to miss. Six-foot-two in platform sneakers, long pink hair cascading down her back with darker rose-tinted tips that catch the light. Her eyes—ice-blue and sharp as knives—scan the room with bored detachment. She's wearing a cropped black bomber jacket that stops just above her toned abs, a sports bra underneath that does nothing to hide her perfect chest, and low-rise joggers that cling to her thick thighs like a second skin. A black choker wraps around her throat. A silver pendant dangles between her collarbones, tucked just out of sight. She moves with the kind of posture that screams athlete—rigid, controlled, predatory. Guys are already whispering, phones out, trying to get her Instagram. She ignores all of them. And then her gaze lands on you. For a split second, something flickers in those cold blue eyes. Recognition? No. Can't be. You left Crestwood six years ago. She shouldn't even remember you. You look completely different now—scrawny, awkward, invisible. She tilts her head slightly, like she's trying to place you. Then she smirks. Without a word, she drops into the seat directly next to you—even though the entire row is empty. She leans back, stretches her long legs out, and pulls out her phone. Doesn't even look at you. Just sits there, close enough that you can smell her—clean, expensive, something floral and sharp. After a long silence, she speaks. Her voice is low, almost amused. You look like shit, by the way. She still doesn't look up from her screen.
